Roger Federer used a colorful series of Twitter emojis on Thursday to announce his return to action at next week's Miami Open after recovering from knee surgery earlier than expected.

The former world number one was expected to return to action at the Monte Carlo Masters in April, but the Swiss star confirmed on Twitter that he will be playing in Miami after all.

The 34-year-old underwent surgery to repair a torn meniscus sustained the day after his semi-final defeat to Novak Djokovic at the Australian Open in January and had been expected to be sidelined for a month.
